 wherein said motion transfer members comprise a driving belt, engaged with said coupling portion of said at least one dragging roller and with said pinion of said electric motor. 
 
     
     
       2. The gymnastic machine according to  claim 1 , wherein the gymnastic machine further comprising a flywheel device comprising
 said flywheel, and 
 a shaft, keyed on one first end with said flywheel, which has a gearwheel, obtained on a second free end, 
 wherein said shaft is arranged in such a way that said gearwheel is aligned with said coupling portion of said at least one dragging roller. 
 
     
     
       3. The gymnastic machine according to  claim 2 , wherein said first longitudinal member has
 a housing and 
 an opening obtained in correspondence of said housing, 
 
       wherein said flywheel, is housed in said housing of said first longitudinal member, and 
       wherein said shaft is arranged through said opening of said first longitudinal member. 
     
     
       4. The gymnastic machine according to  claim 2 , wherein said flywheel device comprises a flange for fastening to said first longitudinal member. 
     
     
       5. The gymnastic machine according to  claim 1 , wherein the gymnastic machine further comprising a flywheel, connected to said at least one dragging roller. 
     
     
       6. The gymnastic machine according to  claim 5 ,
 wherein said electric motor has a rotation axis (AM) and said flywheel has a rotation axis (AV), 
 wherein said rotation axis (AM) of the electric motor and said rotation axis (AV) of the flywheel are parallel and 
 wherein said rotation axis (AM) of the electric motor is arranged below said rotation axis (AV) of the flywheel. 
 
     
     
       7. The gymnastic machine according to  claim 1 , wherein said motion transfer members comprise at least one snub pulley of said driving belt, wherein said at least one snub pulley is rotatably coupled with said first longitudinal member. 
     
     
       8. The gymnastic machine according to  claim 1 ,
 wherein said electric motor has a rotation axis (AM) and said at least one dragging roller has a rotation axis (AR) 
 wherein said rotation axis (AM) of the electric motor, and said rotation axis (AR) of the dragging roller are parallel and 
 wherein said rotation axis (AM) of the electric motor is arranged below said rotation axis (AR) of the dragging roller. 
 
     
     
       9. The gymnastic machine according to  claim 1 , wherein said at least one dragging roller is arranged in a front part or in a rear part of said gymnastic machine. 
     
     
       10. The gymnastic machine according to  claim 1 , wherein said frame comprises at least one horizontal support perpendicularly arranged, and coupled with said first longitudinal member and second longitudinal member, wherein said electric motor is fastened to said at least one horizontal support. 
     
     
       11. A manufacturing method of a gymnastic machine wherein said gymnastic machine comprises a frame having a base, wherein said base comprises a first longitudinal member and a second longitudinal member, a closed-circuit sliding-belt associated with said base, arranged between said first longitudinal member and second longitudinal member, on which a user is configured to execute a gymnastic exercise, and a transmission assembly having an electric motor, configured for moving said closed-circuit sliding-belt,
 wherein said electric motor is arranged below of said closed-circuit sliding-belt 
 
       wherein said at least one dragging roller comprises a coupling portion,
 wherein said electric motor comprises a pinion connected to a driving shaft, and 
 wherein said motion transfer members comprise a driving belt, engaged with said coupling portion of said at least one dragging roller and with said pinion of said electric motor.
